If the so-called 'Zune phone' wasn't already confirmed as being announced at Mobile World Congress 2010, the presence of CEO Steve Ballmer and Microsoft Windows Phone Press Conference, timed for 2pm GMT on Monday February 15th, underlines what's likely to be one of the biggest announcements of the show.

What's actually expected however are details of new operating system Windows Mobile 7, and news about how the platform will integrate with other Microsoft services such as the Zune and Zune HD media players, which already allow access to Xbox Live and the Zune Marketplace.

The press conference will be streamed live from Microsoft's news center.

We certainly hope Steve will be on top excitable form.

"Developers, developers, developers..."
